Clarity is the point
Filter coffee is less concentrated than espresso, so muddy roasting has nowhere to hide. A good listing should give you a sense of origin, process, acidity, sweetness and likely cup style before the bag reaches your grinder.
Filter brewing is unforgiving in a useful way: it shows roast, processing and origin character without much cover. The best filter coffee beans UK roasters sell are often lighter than classic espresso, but they still need sweetness and structure. This page sets out what to look for before you buy for V60, AeroPress, Chemex or batch brew.
Look for beans recommended for filter, pour-over, AeroPress or both main brew styles.
Expect light to medium roasts, clear tasting notes and proper origin information.
Choose fruity or floral coffees for brightness; sweet or cocoa-led coffees for a calmer cup.
Read process notes, because washed, natural and anaerobic coffees can taste wildly different.

V60 and Chemex can flatter delicate, citrusy and floral coffees. AeroPress and batch brew are more forgiving, so they suit sweet, rounded beans with cocoa, caramel or stone-fruit notes.
A good filter roast should still have sweetness and structure. If your brew tastes sharp, try grinding finer, using hotter water or choosing a slightly more developed roast next time.

You can, but espresso roasts often taste heavier and less clear as filter. Beans marked for filter or both brew methods are a safer choice when clarity is the goal.
Light to medium roasts are common for speciality filter because they keep acidity and origin character in view while still offering sweetness.
